I remember getting something like that



Yeah I expanded using normal double angle and simplified. At first I tried changing to sin and cos but that screwed me over, so I ended up playing with just tans and i got it.

hi nath (dont ask me how i know u lol)
do you remember the induction divisibility.. i wanna redo to assure myself i got it right... also the EGAD one

for polynomial did u get for 1 roo x =2, k = -10 and the otehr 2 roots like 5 and -1? =]

Was k=10. I know it was either k=-10 or 10.

 

[lyounamu]

Was k=10. I know it was either k=-10 or 10.

I think ur right. I got 5, -1 as other roots and 2 in the middle.

To everyone: In saying that, I don't remember 100% correctly.

About proof question on tan, u just expand - easy shit.

 

[Aquawhite]

I was so close to getting that bloody question >_<... it just shows me what I need to practice!

it was ta2x - tanx on top yeh?? i freaking wrote tan2x + tanx =/

 

[kwabon]

piece of cake.

 

[lyounamu]

it was ta2x - tanx on top yeh?? i freaking wrote tan2x + tanx =/

i dun remember the question.

but in the end i got something like

(tan^3(x) + tanx)/(tan(x) + cot(x))
= tan^2(x)

@kwabon: agreed man. what do u reckon u got? 84? xD

For the inverse function did you have to draw it or find the equation?

both

both

fuck.

 

[bored of sc]

Loved questions 1, 2 and 6. Disliked parts of the rest and despised 7. If I can manage 70% I'll be glad. Hopefully minimal silly errors can get me through.

I do agree with the people who said it was a relatively easy test. Most of it was straight forward. But under the pressures of a exam situation you are suspectible to making some silly choices, careless mistakes etc.

Someone aware me on the hilarity of the circle geo question.

 

[spauka]

Hey
Overall good exam, hoping 76+, but awful time management. For the last probability question, the binomial one (50 multiple choice, 0.3 chance of correct), the non-accelerants havent done binomial yet, so the topic was supposed to be removed, but the maths coordinator was damn sure there was a permo's and combo's way of solving the question. Does anyone know what it is, cause i just solved it using binomial, and could NOT figure out the other way. Apart from that, pretty good exam. Not too hard, not too easy.

 

[crystalfishy]

lol i think this circle geo was replaced in my paper..i didnt look at it since it was crossed out
wat was it?

 

[ibrian]

was k=1 or 2?
and did you have a 'h' in ur dSA/dt, and how are you meant to get rid of it

 

[AnandDNA]

I got 1

 

[shaon0]

Ridiculously easy that it's funny?

I didn't find it funny at all...

lol. I had to do that at the end because i couldn't get it first time around.

 

[shaon0]

I got 1

Yeah. I think i also got k=1.

 

[-Onlooker-]

Yeah. I think i also got k=1.

Answer was k=2; I'm certain.



And to the guy asking about how you get rid of h, we are given h=kr; you work of that if i remember correctly.

 

[shaon0]

Answer was k=2; I'm certain.



And to the guy asking about how you get rid of h, we are given h=kr; you work of that if i remember correctly.

do u remember the exact question? I could solve it again to find the correct answer. I'm sure the answer was either 1 or 2. I just can't remember which one.
